8 miles of shoreline
200 square miles of water
8 official lighthouses and 8 historic forts
13 municipalities from Cape Elizabeth to Phippsburg, including Long Island and Chebeague Island, abut Casco Bay.
1 in 5 Mainers live in the 42 communities of the Casco Bay watershed, from Bethel to the Bay.
1989 Friends of Casco Bay was founded to improve and protect the environmental health of Casco Bay.
1990 Casco Bay was designated an Estuary of National Significance under the Clean Water Act.
With the arrival of spring, we hope you seize the Bay by getting outside to enjoy our 578 miles of shoreline, taking in that 200 square miles of water, and visiting those lighthouses and forts!
